When combined with water, soapless detergent becomes a cleaning agent, capable of dissolving grease, disinfecting and removing particles from the surface it is cleaning. If detached oil droplets and dirt particles did not become suspended in the detergent solution in a stable and highly dispersed condition, they would be inclined to or coalesce into large enough to be redeposited on the cleansed surface.
